A Natural Quinazoline Derivative from Marine Sponge Induces Apoptosis of Breast Cancer Cells via ROS Production and Intrinsic or Extrinsic Apoptosis Pathways.

Here, we report the therapeutic potential of a natural quinazoline derivative (2-chloro-6-phenyl-8H-quinazolino[4,3-b]quinazolin-8-one) isolated from marine sponge against human breast cancer. The cytotoxicity of the compound was investigated on a human breast carcinoma cell line (MCF-7). Antiproliferative activity of the compound was estimated by 3-(4,5-Dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay.

Proteomic changes in the liver of Channa striatus in response to high temperature stress.

The present study was undertaken to investigate the proteomic changes in the liver of murrel Channa striatus exposed to high temperature stress. Fishes were exposed to 36°C for 4 days and liver proteome changes were analyzed using gel- based proteomics, i.e.

Proteomic profiling of white muscle from freshwater catfish Rita rita.

Muscle tissues contribute 34-48 % of the total body mass in fish. Proteomic analysis enables better understanding of the skeletal muscle physiology and metabolism. A proteome map reflects the general fingerprinting of the fish species and has the potential to identify novel proteins which could serve as biomarkers for many aspects of aquaculture including fish physiology and growth, flesh quality, food safety and aquatic environmental monitoring.
